Simultaneous simulation of pathogen inactivation and bromate formation in full‐scale ozone contactors by computer software
Ozone contactor model (OCM) software was developed as an innovative tool for full‐scale ozone bubble‐diffuser contactor design and optimization in support of current and future regulations regarding pathogen and bromate control in drinking water. The software is based on the reactive transport model that has been experimentally verified with lab‐, pilot‐, and full‐scale ozone contactors in previous studies. The OCM is designed to be user‐friendly with graphical user interfaces and operates on personal computers so that users can perform complex simulation tasks under various design and operating scenarios without extensive training. The details of software structure and usage guidelines are provided in this article. Demonstrative application of the OCM for simulating the performance of a full‐scale ozone contactor with respect to Cryptosporidium parvum oocyst inactivation and bromate formation was performed using experimental results obtained from the Linnwood Water Plant Ozone Facility (LWPOF) at the Milwaukee (Wis.) Water Works. The model was further applied to simulate the performance of this ozone contactor at different operating temperatures. The simulation results suggest that meeting inactivation requirements for C. parvum oocysts is more challenging at lower temperatures, while controlling bromate formation is more challenging at higher temperatures. Additional simulations suggest that ozone contactors be designed with the lowest possible dispersion in order to achieve target inactivation efficiency with minimum formation of bromate.
